Public opinion significantly affects foreign policy decisions by reflecting the values and priorities of citizens that elected officials must consider. High-profile events, such as wars or humanitarian crises, may lead public sentiment to sway dramatically, placing pressure on policymakers to respond in ways that align with popular opinion. This responsiveness can enhance democratic legitimacy but can also lead to inconsistencies in policy if elected officials prioritize short-term sentiment over long-term strategy. Ultimately, public opinion serves as a powerful barometer for foreign policy, shaping national agendas and influencing diplomatic approaches.
